iPhone App for Vessel Log Book?

[AquaticaSD]

I'm looking for recommendations on a iPhone (IOS) vessel Log Book. For it to meet my needs, it should accomplish the following:

1. Trip Logging - Dates: engine hours start/finish, origin, destination, crew, comments, ...
2. Inventory of equipment - make, model, serial #, service notes
3. Regular maintenance/supplies - Dates/hours:fuel, water, key stores, spare parts on board
4. Engine/system maintenance - Dates/hours:Actions (repair/replace/service) organized for quick identification of related service

I'm guessing that someone (much brighter than me) has gone through the organization and logging of key data to make this a simple, but thorough log with the least amount of typing - as making a text entry is not very easy on an iPhone. I do have an iPad and Mac computer, but those aren't always available for data entry - but it could be very useful to be able to access this data from a cloud repository.

I'd appreciate any recommendations, thanks.
